Specification of Letters Patent.

Patented July 1s, 1909.

Application filed July 1, 1908. Serial No. 441,274.

To all whom t may concern: l

Be it known that I, FRANKLIN P. EAST- MAN, a citizen of the UnitedStates, and resident of the city of New York, borough of Brooklyn, inthe county of Kings and State of New York, have invented a new andImproved Dumping-Scow, of which the following is a full, clear, andeXact description.

The invention relates to dumping scows, such as shown and described inthe Letters Patent of the United States, No. 629,554, granted to me July25, 1899.

The object of the present invention is to provide a new and improveddumping scow, having movable` sides normally securely locked againstopening, and which can be readily opened without presenting obstructionsto the load, thus insuring a complete and quick discharge of the load,especially when the latter consists of bulky and moist refie liable tocling to any obstructions in its )at l The invention consists of novelfeatures and parts and combinations of the same, which will be morefully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in theaccompanying drawings forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure l is a plan view of a dumping scow having two pairs ofcompartments, of which one pair is shown closed and the other open; Fig.2 is an enlarged cross section of the improvement on the line 2 2 ofFig. l; Fig. 3 is a similar view of the same on the line 3 3 of Fig. l;and Fig. Il is a like view of the same and showing one of the sidespartly open.

To the framework A of the dumping scow is attached a bottom B andinclined floors O, C, forming a peak-shaped section eXtending centrallyand longitudinally from one end D of the scow to the other end Dthereof, as plainly indicated in Figs. l and 2. One or more bulkheads Emay be arranged transversely on the scow, to give the desired strengthto the structure and to form with the floors O and the movable sides F,com partments for receiving the refuse, each compartment having a sideor door F which can e opened for allowing a load to slide down thecorresponding lioor O into the water.

The lower ends of the sides F are adapted 4to engage hooks or similarretaining devices G attached to the lower ends of the floors O, and theupper ends of the sides F are pivoted on transversely extending supportsH in the form of beams mounted to slide in suitable bearings arranged inthe upper portions of the floors O, as plainly indicated in Figs. 2 and3. The inner ends of the supports H are provided with racks H and thesupports H of two oppositely arranged sides F having their racks H inmesh with opposite sides of pinions I secured on a shaft J extendingengthwise of the scow and journaled in the framework A immediately belowthe ridge of the peak-shaped section, as plainly indicated in Figs. 2and 3. In practice, I prefer a shaft J for each pair of compartments andeach shaft J is provided at one outer end with a suitable turning deviceK, such as a pawl and ratchet mechanism, as indicated in Fig. l.

Arms L are pivotally connected at their lower ends to the lower ends ofthe floors O, and the upper ends of the said arms L are pivotallyconnected with the supports H a distance inward from the pivotalconnection of the sides F with the supports H, as plainly indicated inFigs. 2 and Now when the sides F are closed, as shown in Fig. 2, thenthe compartments thus formed can be iilled in the usual manner, and whenit is desired to discharge the load, it is only necessary for theoperator to turn the corresponding shaft J, by actuating the ratchetmechanism K connected with the shaft, so that the pinions I im art anoutward traveling motion to the rac rs H and to the supports H. N owduring this outward travel of the supports H, the arms L swing outwardand thus lift the outer ends of the supports H slightly and with themthe sides F, which also assume an inclined position, as shown in Fig. 4,the lower ends of the sides F finally leaving the retaining devices G,to swing into an open position, as indicated. in Fig. 3. N ow when thistakes place, the load in the opened compartments readily slides down theinclined floors O into the water surrounding the scow. By the use of thesupports H andthe arms L the sides F can be readily swung into an openposition, without requiring much physical exertion on the part of theoperator turning the shaft J, so that practically it requires but littlehelp to move the sides F into an open position for dumping the load ofthe scow. K It will also be noticed th'at the load is dischargedsimultaneously from both sides of the scow, as. the corresponding sidesof a pair of compartments open at the same time. By turning the shaft Jin an opposite direction the supports H are moved inward, to allow ofclosing the sides F, whenever it is desired to refill the compartmentsof the scow with another load.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

l. A dumping scow provided with movable sides, transversely movablesupports on which the said sides are hung, and links pivotally connectedwith the scow and pivotally connected with the said supports at a pointinward from the connection of the said sides with the said supports.

2. A dumping scow provided with movable sides, transversely movablesupports on A the outer ends of which the said sides are hung, retainingdevices on the scow for engagement by the lower ends oi the said sides,links pivotally connected at their lower ends with the said scow at thelower end of the lioor and pivotally connected at their upper ends withthe said supports at a oint in-. ward of the pivotal connection of t iesides, and means for imparting an outward movement to the supports, tocause the links to swing outward thereby lifting the outer ends of thesup orts and the said side to release the latter trom the retainingdevices.

3. A dumping scow provided with an inclined floor, transversely movablesupports on the scow, a side hung on the said supports, retaining meansiiXed on the lower end of the said floor and adapted to be engaged bythe lower free end of the said side, and

arms pivotallyl connected with the scow, and with the said supports,`the connections of said arms with the supports being inward of theconnection of' the side with the supports, and the said arms inclininginwardly when the side is in closed position, whereby when the supportsare moved outwardly the outer ends of said supports are liftedto'disengage the side from the retaining means.

4. A dumping scow provided with an inclined floor, transverselyextending supports provided with racks, a shaft extending lengthwise 6ithe scow, pinions on the said shaft and in mesh with the said racks, aside hung on the outer ends of the said supports, and arms pivotallyconnected with the scow at the lower ends of the said floor, andpivotally connected with the said supports a distance inward from theconnection of the said side with the said supports,

5. A dumping scow provided with an in-V clined floor,transversely-extending supports provided with racks, a shaft extendinglengthwise of the scow, pinions. on the said shaft and in mesh with thesaid racks, a side hung on the outer ends of the said supports, armspivotally connected with the scow at the lower ends of the said lloor,and pivotally connected with the said supports a distance inward fromthe connection of the said side with the said supports, and hooks on thelower end of the said ylloor and adapted to be engaged by the lower endof the said side.

6. A dumping scow provided with inclined l'loors, transversely extendingsupports mounted to slide in bearings in the upper portions of thefloors, sides hung on the outer ends of lsaid supports, arms pivotallycon-4 nected with the lower ends of said lloors and pivotally connectedat their upper ends with the said supports, the connections of said armswith the supports being inward of the connection of the sides with saidsupports, a shaft extending lengthwise of the scow and journaled in theframework, and means for imparting a traveling motion to the saidsupports from the said sh alt.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
